I am a Professor of Quantitative Psychology at The Ohio State University. My research focuses on linear models, with an emphasis on resampling methods of inference. Specific areas of investigation and writing include statistical approaches to assessing mediation and moderation. I hold a Ph.D. in Psychology from Cornell University (1996) and a B.A. in Psychology from San Jose State University (1991).

Over the years I have taught various classes on data analysis primarily at the graduate level. Courses include Introductory Statistics, Multiple Regression, Moderation and Mediation Analysis, and Structural Equation Modeling. I regularly conduct workshops on moderation and mediation analysis at institutions throughout the world. I also teach regularly for Statistical Horizons and the Global School in Empirical Research Methods.
